Like… I can’t even imagine something this small. How can you produce a transistor smaller than 10nm, especially billions of them all working flawlessly?
I understand that CPUs have cores disabled due to manufacturing defects but… even so we’re talking about what feels like a mind-boggling level of precision.
How is it done?
In: Engineering
The first thing to understand is that the name of the process is all marketing. There’s nothing that actually measures 3nm or 5nm in any of the transistors. It used to be a physical feature that you could measure but it stopped several years ago
The second is that it generally works by etching patterns into the silicon. The lasers don’t actually have the precision to move from transistor to transistor anymore cus they are so close and the distances are so small. So instead, they etch the first line, move over, etch the first line of another one, etc. then wrap back around to the beginning and etc the second line.
